At present I don't see any compelling reason to involve multiple big bangs in our model of the big bang---the start of expansion. Pending evidence to the contrary I expect one start of expansion, operating under one set of fundamental highenergy laws of physics will probably fit the data.

Well, it kinda has to. But that same model may unambiguously predict other bangs, other low-energy laws of physics (our current model already predicts other low-energy laws of physics...and other bangs are the natural expectation of any model that produces at least one).
Now, I don't think there is any conceivable way that we will ever be able to obtain direct evidence of universes with different fundamental laws. Though I do think it may be interesting to think about the possibility.
